This commit fixes a test exercising complex numbers creation, working around a deprecation introduced in CPython 3.14. Creating complex numbers using a complex number as the real part in the constructor is deprecated in CPython 3.14, but that construction method is still supported by MicroPython and covered by tests. To work around this, the specific constructor is extracted into its own test, providing an expected output file recorded using CPython 3.11. Signed-off-by: Alessandro Gatti <a.gatti@frob.it>
